We may not be lucky enough to get a full-on musical episode in Season 5 of Castle, but according to actor Jon Huertas, there will be singing — and it won't be Tamala Jones with the microphone this time!Instead it'll be Lanie Parish's on-again-off-again booty call, Detective Esposito! "There's a case with a band, which I thought was really amazing," Jon told Wetpaint Entertainment in an exclusive interview. "They gave us an opportunity to really play with how we film the show, and they allowed me to actually sing in the episode on camera in front of everybody. It's a lot of fun. You're going to love it!"

Jon certainly has the vocal chops to pull it off. Last year, he released his debut single, "Sex is the Word," showcasing his musical (and sexual!) prowess, and more recently he lent his skills to Roc$stedy's music video "Waste of Your Time."

Tamala gushed about the episode as well, dropping some more hints about what to expect.

"Oh my God, the death is crazy!" she teased in an interview with The Insider. "It involves a rock group and it's the first time you'll see all the characters having to play to the camera [because] it's a rock documentary. As actors you're taught not to look at the camera, so we're all freaked out."
